I'm using version 6.11.10.1608 to view .psdata files, placing the rulers over various waveform arrival points (I'm plotting arrival times for seismic waves through rock samples), then exporting the graph to a plot, and saving the .psdata file so I keep a record of where I'd placed the rulers to mark arrival times.

However, occasionally when I hit the save button, the file is instead being deleted. Are there any other reports of this? (I'm not losing the original data, as there's a backup on another pc in the lab that I originally tested the samples with.)
